In Switzerland January'4,1935Y 6 claims. (o1. 139-84) In weaving loomswithout superstructure, -as well as in looms with superstructure,freedom of movement of the healds is an indispensable requirement. Themodern tendency in weaving loom construction-especially in connectionwith silk weaving-is to reject looms with superstructure, since thelatter impedes supervision and accessibility; moreover, particles of oiland dust and so forth falling on the warp and other cir- 10 cumstancesrelated to the access of light have an unfavorable effect upon thequality of the goods and the efficiency of the Weaving.

On the other.hand, weaving looms without superstructure and withdownwardly pulled healds have not established themselves in practiceowing to constructional defects and undue stiffness of the healdmovement occasioned by positively guided operating arms, which haveprevented all freedom of movement of the healds.

Now, the present invention provides, in a weaving loom having a freespace above the reed and the harness, the feature that thek guide andpull members adapted to operate the healds in a suspended manner, aredisposed laterally atV 2B heald level. This arrangement, while retainingthe greatest possible freedom of movement of the healds, greatlyfacilitates the handling of the aforesaid members, e. g. when attachingthe Aharness cones and heald operating levers, inasmuch as these membersare located'about half as high from the ground as hitherto.

The accompanying drawing shows two typical embodiments of the invention.

Fig. 1 shows an example for two-heald or plain fabric; and

Fig. 2 one for dobby weave fabric, that is fabrie woven by means ofdobby controlled healds.

In the weaving loom with free space above the loom and the harness shownin Fig. 1, a indicates 0 the -top beam, a) the lowerbeam of the healdframes,ra2 the side walls of the same, b two screws disposed laterallyon each of the said frames for adjusting the 'position of the healds andthe size of the shed, c two pull chains, d two guide rollers, journalledupon pivots parallel to the warp and e two harness operating cones. fdenotes the means for controlling the position of the heald frames. Itwill be seen that the healds have the greatest possible freedom ofmovement laterally and in warp direction and that the harness operatingcones may be attached at heald level, whereby the connection of theharness cones is considerably facilitated. In other words the point ofattachment l 56 of the cones e to the chains c is within the range ofmovement of the heald frames. The springs do not hinder the swingingmovements of the healds.

In the example according to Fig. 2, for dobby weave fabric, a againdenotes a heald frame, b 5 the adjusting screws for the healds, c thepull chains, and d the guide rollers. el denotes a dobby operatedshedding lever, and j the springs for returning the heald frames to thelowermost y position. Here too, the healds have the greatest 10 possiblefreedom of'movement, and the operating levers of the dobby may beattached at heald level foi/facilitating the handling.

What I claim is 1. A weaving loom comprising a plurality of l5 4healdframes consisting of an upper top beam,

heald frames consisting of an upper vtop beam,

a lower beam and connecting side walls, shafts extending laterally tothe side walls of the beams and parallel to the warp, guiding pulleyssupported by the shafts and being disposed at a 30 level withfthe topbeam, pull members passing over the guiding rollers, beingl connected tothe side walls of the heald frame and supporting the latter in asuspended manner at a point situated beneath the top beam. 30

3. A weaving loom comprising a plurality of heald frames, consisting ofan upper top beam, a lower beam and connecting side walls, shaftsextending laterally to theside walls of the beams and parallel to thewarp, guiding pulleysV sup- 40 lported by the shafts and being disposedat a level with the top beam, pull members passing over the guidingrollers being connected to the side walls of the heald frame andsupporting the latter in a suspended manner, at a point which 45 issituated underneath the top beam about one third of the distance betweenthe two beams.

4. A lowv built,` compact loom comprising a plurality of heald framesconsisting of an upper top beam, a lower beam and connecting side 59walls, shafts extending laterally to the side walls of the beams andparallel to the warp, guiding pulleys supported by the shafts and beingdisposed at a level with the top beam, pull memhere and harness frames,the pun members be- Y ing disposed laterally of said harness frames andpassing over the guiding rollers, said pull members also being connectedto the side walls of the heald frame and supporting the latter in asuspended manner.

5. A low-built and compact loom comprising a plurality of heald framesconsisting of an upper top beam, a lower beam and connecting side walls,shafts extending laterally to the side walls of the beams and parallelto the warp, guiding pulleys supported by the shafts and being disposedat a level with the top beam, pull members and harness frames, the pullmembers being disposed laterally of said harness frames and passing overthe guiding rollers, said pull members also being connected to the sidewalls of the heald frame and supporting the latter in a suspendedmanner, at a point located below the top beam.

6.
